Graph of the temperatures during a complete cycle of cooling down and warm up on BIRCAM. Cold finger is located behind the detector. Optical bench sensor is located next B lens in Figure 2. The first part (first band, about 5 hours) is the cooling down phase, the second part (second band, until first 24 hours) is the stationary cold phase, the last one (about two days and half) is the warm up phase.
